PATENT WILLIAM D. HUGHES, OF GRANVILLE, NEW YORK, ASSIGNOR OF ONE-HALF TO JOHN T. WILLIAMS,OF BROWNVILLE, MAINE.

NUT-LOCK.

` SPECIFICATION'VfOrming part of Letters Patent NO. 700,651, dated May 20, 1902.

Application led October 19, 1901. Serial No. 79,287. (No model.)

To all whom, it 77u01/ concern.-

Be it known that I, VILLIAM D. HUGHES, a subject of the King of Great Britain, residing at Granvi1le,'in the county of Vashington and State of New York, have invented certain new and useful Improvements in Nut- Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This-invention relates to nut-locks, and has for its object the production of a device of this character which will greatly lessen the cost of constructing railroad-joints by obviating the necessity of providing fish-plates with fastening means for securing the locking-bar thereto and forming the nuts with iianges in order that the locking-bar may prevent their turning. v

Further objects of the invention will appear as the nature thereof is more` fully understood from the following description.

The invention consists in the -novel -construction, combination, and arrangement of parts, as will be hereinafter fully described and claimed, andillustratedin the accompanying drawings, in whichf Figure l is a side elevation of a portion of a rail and fish-plate, showing my improved nut-lock applied thereto. Fig. 2 is a sectional view on 'the line 2 2 of Fig. l. similar view to Fig. l with the locking-bar and nut removed. Fig. 4 is a detail plan of one end of the washer.

l designates a portion of a railsection broken away at a point near one of its ends,

and 2 the fish-plates, one of which is pro-v vided with a longitudinal groove 2a. The

rails and sh-plates are secured togetherin.

the usual manner by bolts and nuts, one of which only is shown, S-designating the. bolt and 4 the nut.

5 designates awasher,y preferably oblong in form and adapted to be secured between the fish-plate and nut against movement. The

Fig. 3 is av to prevent the washer from tilting vertically upon'the bolt,'and also to hold said fianges locking-bar 10, and is provided with perforationsl through which pass suitable fastening devices to secure said bar thereon.

The locking-bar 10 is provided with suiti able openings, through which extend the lugs 9, and has a nut-receiving opening l1, which may be of any preferred form, depending upon the form of the nut to be locked.

It is obvious from the above description, taken in connection with the accompanying drawings, that the flanges 7, iniitting in the groove 2, will hold the washer, which is mounted upon the bolt 3, against movement, and the bar l0 in locking the nut 4: upon the bolt holds the anges in the groove, thus 0bviating any liability of the nut becoming loose. It is further obvious that I greatly reduce the cost of a nut-lock and also obviate the necessity of providing the fish-plate with means for holding a locking-bar and obstructing-nuts with shoulders in order that the locking-bar may prevent their turning.

This nut-lock is not restricted to use upon rails, but may Y be employed wherever the -flanges may secure a grip to hold the Washer against movement.

Having described my invention, what I claim is- The combination with a rail, a bolt carrying a nut, and a sh-plate having a longitudinal groove and secured upon the bolt between the nut and rail, of a Washer secured upon the bolt between the fish-plate and nut, the washer having its ends bent at right angles to fit in the groove andprovided with an enlarged bearing-surface against which the nut bears preventing the washer from tilting upon the bolt and to hold'the anges in the groove, lugs upon the washer, and a locking-bar having a nut-receiving opening and secured upon the lugs.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM D. HUGHES. Vitnesses:

THOMAS J. PARRY, DAVID D. WILLIAMS.
